It's tempting to buy the big bag of celery at Costco but you'll seldom use it all by the time it starts to fade. If you wrap the celery in a plastic bag and then wrap that bag in aluminum foil you can get a much longer refrigerated shelf life.

Prepper weblog Preparing One Day at a Time claims they've kept celery fresh using this technique for more than a month. I can't verify that as of right now, but next time I go to Costco I'm going to give it a try.
